The study found that despite some DNA damage to the sperm from room radiation which is 100 times stronger than that on Earth the mouse sperm and baby fared reasonably similarly to controls.

The sperm was kept in chamber temperature in space and likely could be preserved similarly for humen in the future no need for a freezer. That’s a boon for weight-conscious launchings to the space station.

The results of freeze-drying mouse sperm and sending it to room are normal mice babies.

“Sperm preservation in the event of disasters on Earth will be an important tool for retaining the genetic diversity of mammalian species, much like flower seed preservation in the Svalbard Global Seed Vault, ” the study writers wrote.

Beside procuring a good sperm preservation technique, these mice show that if( or when) humen start living in space or colonizing other planets, the human race might be able to survive.
